Abstract (en)

[origin: US2013255495A1] Disclosed herein is a method comprising contacting a residual flue gas stream with a lean solution stream in an appendix stripper; where the residual flue gas stream comprises nitrogen, oxygen and moisture; and where the lean solution stream comprises ammonium, ammonium carbonate, ammonium bicarbonate and ammonium sulfate; forming a vapor phase that comprises ammonia vapor, water vapor, carbon dioxide and nitrogen; forming a liquid phase that comprises water, ammonium sulfate and ammonia; discharging the vapor phase to a capture system; and discharging the liquid phase to a direct contact cooler.
